May I ask whether the platform IDE or avrdude and other tools are faulty? It would be much appreciated if this could solve the problem. My development board model is Arduino UNO R3.
After PlatformIO is burned, it will be stuck at the following code when executing the program:
u8g2.firstPage(); do{ u8g2.setCursor(0, 0); u8g2.setFont(u8g2_font_ncenR12_tf); u8g2.setCursor(10, 35); u8g2.print(“Waiting”); } while (u8g2.nextPage()); delay(200);
The complete code is as follows:
#define BLINKER_BLE
#include <Arduino.h>
#include <SPI.h>
#include <Wire.h>
#include "U8g2lib.h"
#include <Blinker.h>
#include <Adafruit_Sensor.h>
#include <DHT.h>
#include <MFRC522.h>
#include <IRremote.h>
#define DHTPIN 7 // 指定 DHT11 数据引脚
#define DHTTYPE DHT11 // 指定传感器类型为 DHT11
float temp, humi;
bool mark = false;
